Since McDonald's arrest Monday on misdemeanor domestic violence and child endangerment charges, Bears chairman George McCaskey has considered his role in allowing McDonald to be signed as a free agent in the first place after two previous arrests, and what he can do from here to safeguard the team. McCaskey spoke to reporters Wednesday for the first time since the incident — of his regrets, and what he has learned.

"Domestic violence is a vexing social problem. The NFL has had some high-profile cases, including this one. And the NFL, because it's a leader in society, is called upon to take action. Which we are doing. We're not going to do it by ourselves. But I think we have an opportunity to make an impact."

According to the 911 call placed by the alleged victim's mother on behalf of her daughter, McDonald was inebriated and his ex-fiancee' — the mother of McDonald's child — felt unsafe. The caller tells authorities that he broke down a bedroom door and tried to take the child. It was 3:48 a.m., and McDonald was arrested at 7 a.m. at the home of former teammate, Justin Smith. McDonald's attorney, Steve DeFilippis, told the San Jose Mercury News that the couple argued, but denied allegations of assault. McDonald has been released on $15,000 bail.

The incident, DeFilippis says, was witnessed by McDonald's driver and the the alleged victim videotaped at least part of it.

The details will matter in a court of law. They are irrelevant to the Bears, who signed McDonald to a one-year contract with the demand that he steer clear of even the hint of trouble.

Asked if he regretted his decision, McCaskey said: “I’ve asked myself that question a lot. What more could I have done? Is there somebody else that we could have consulted with? Should I have taken more time to make a decision? I don’t know. We thought we had a good structure, a good support system and we thought we had the safeguards in place in case something like this happened.”

McCaskey said he wasn't consulted by general manager Ryan Pace before McDonald was released.

"I wasn't involved because I didn't need to be," he said. "They knew what needed to be done and did it."
